An enclosed amount of nitrogen gas undergoes thermodynamic processes as follows: from an initial state A to a state B to C to D and back to A, as shown in the P-V diagram. Assume that the gas behaves ideally. (a) If the process A-B is isothermal, determine the pressure of the gas in the state B. (b) Calculate the heat transferred to the gas in the process A-B. (c) Calculate the work done on the gas, the heat transferred to the gas and the change in internal energy for the process B-C. (d) What is the change in internal energy of the gas for the entire process, A-B-C-D-A? point A(0.10,13.0) point B(0.12, P) C(0.135, 5.00) D(0.10, 5.00)(V, P)
